Answer:

1 quarter = 1/8 Toonie 20 quarters = 2 1/2 Toonies 24 quarters= 3 Toonies

Step-by-step explanation:

Plz vote brainly for a competition with my friend. What I did with the equation is look at quarter to toonie ratio. It is exactly 1 toonie to 8 quarters. With that you can simply deduce the correct answers per quarter number

Aye I gotchu. Okay to do this just divide each left side by 8. For example 1= 1/8.

Assume that the Poisson distribution applies and that the mean number of aircraft accidents is 9 per month. Find P(0), the prob

Ugo [173]

Answer: 0.0001

It is unlikely to have a month with no aircraft accidents .

Step-by-step explanation:

Given : Mean number of aircraft accidents = 9 per month

The Poisson distribution formula :-

$\dfrac{e^{-\lambda}\lambda^x}{x!}$ , where $\lambda$ is the mean of the distribution.

If X = the number of aircraft accidents per month, then the probability that in a month, there will be no aircraft accidents will be :-

$\dfrac{e^{-9}(9)^0}{0!}=0.000123409804087\approx0.0001$

Hence, the probability that in a month, there will be no aircraft accidents = 0.0001

Since this is less than 0.5 , therefor it is unlikely to have a month with no aircraft accidents .

Please answer I’ll rate brainlyest

Answer:

$5P3*6C4=60*15=900$

Step-by-step explanation:

$5P3$ refers to the permutations of 5 items taken 3 at a time. To evaluate this, we use factorials as follows;

$5P3=\frac{5!}{(5-3)!}$

The factorial of an integer n is evaluated as;

$n!=n*(n-1)*(n-2)*(n-3).......3*2*1$

Using this concept, the above expression can now be simplified as follows;

$5P3=\frac{5!}{2!}=\frac{5*4*3*2!}{2!}=5*4*3=60$

Therefore, the permutations of 5 items taken 3 at a time is 60.

The next expression, $6C4$ refers to the combinations of 6 items taken 4 at a time. The simplification utilizes similar concepts of permutations since we shall be involving factorials;

$6C4=\frac{6!}{4!(6-4)!}=\frac{6!}{4!*2!}=\frac{6*5*4!}{4!*2*1}=\frac{6*5}{2*1}=15$

Therefore, the combinations of 6 items taken 4 at a time is 15.

The final step is to evaluate the product;

$5P3*6C4=60*15=900$

PLEASE HELP!!!

Ksju [112]

ANSWER

$a = 1,2,3,6$

EXPLANATION

The given equation is

$ax = 6$

Divide both sides by $a$

$\Rightarrow \: \frac{ax}{a} = \frac{6}{a}$

Cancel out common factors on the left hand side,

$\Rightarrow \: x = \frac{6}{a}$

For this solution to be a whole number, then $a$ should be a factor of
$6$ .

The reason is that, factors of 6 will divide exactly in to 6 without a remainder, making the answer a whole number.

The whole numbers that are factors of 6 are,

$1,2,3 \: and \: 6$

Note that, the set of whole numbers are,

{ $0,1,2,3,4,...$ }
